2021 Y CCS Upgrade DIY: My experiance

[jamieorc]

I did this upgrade this morning. The hardest part was disassembling and reassembling the interior. Be careful with clips and the smaller electric wiring connector for the seat release.

After I used service mode to reinstall the software. No problems.

Tested on 120 volt charging, ChargePoint L2 and ChargePoint CSS. All working fine.

I did not disconnect any batteries. As others noted, the service manual does not require this.

Neat! How much did this cost you?

I don’t recall the exact number but about $150.
